Hempy, you're assuming he actually played some before deciding they're all crap? I think you're giving him too much credit.(btw, I can't believe you missed Drox Operative from your list, personal taste I guess...)

To me, I wouldn't say that Greenlight games are all "awful", but I think that it's fair to say that a huge number of them are pretty disappointing.

By this I mean a good number of them lack any kind of creativity. For example, it doesn't take long to find a platforming game with a bunch of jumping puzzles and no new mechanics. Or a procedurally generated horror game where most of the scary parts are jump scares. Etc. Another problem is that several games have really questionable amounts of effort put into them. That is, they are either poorly or barely animated, flat textures, etc.

I'll just put it this way. If all of the creators were applying for a job or they were trying to start a Kickstarter, then I wonder how many of them would show off their current game submission as proof of their talent. I'm sure most of them would, but there's definitely some submissions that would be immediately hidden or quickly dismissed as a creative experiment. It's those submissions that make me wonder why they are here in the first place.

Different types of games attract different people. Most of the games I am developing are educational, that focus on teaching a particular subject, but intertwine that with gaming fun. I know that will not appeal to the masses, but there is a niche for it. I get some thumbs down, maybe a higher percentage that the big timers, but I serve a niche. Developers have to find something original to attract those of the traditional genres, or find a new genre to serve.

Random people spent 2 hours in creating an abomination of a game. Then they post here some fancy screens and a video.Then those troll devs get some troll voters.Next, the game get´s greenlit because of all the troll votes.In the end the troll devs feel satified and we have one more game abomination on steam.

MinisterJay probably got closest in his first line (before he went all a bit self-promotion-y) but the real answer is probably down to that age old problem... You can't understand the concept that other people like things that you don't like.

I know it's a lot to take on and you'll probably have to really work at it to fully understand the scope of the idea and how it's affected you all your life but please try. Once you've grasped that, a lot more things will make sense and you won't find yourself coming up with silly theories about a handful of trolls moving mountains.

the other 8/10 have been greenlit through troll votes and bought chinese slave voters.

If they have that kind of money to sponsor premium Steam accounts (accounts that has bought at least one game) in those ammounts (plus paying the chineese people for their vote), why would they go through Greenlight? They could just make a publishing company, publish a few games by other people and get their game onto Steam that way.
